The correct two-way frequency table for the date will look like this:
RAP ROCK COUNTRY TOTAL
Grades 9-10 40 30 55 125
Grades 11-12 60 25 35 120
TOTAL 100 55 90 245
The sum of the row total is equal to the sum of the column total
125 + 120 = 100 + 55 + 90
245 = 245
9514 1404 393
Answer:
Step-by-step explanation:
a) You go about this by using the given equation.
Left + Right = Total
JK + KL = JL
(2x -3) + 11 = 4x
8 = 2x . . . . . simplify, subtract 2x
4 = x . . . . . . divide by 2
__
b) JL = 4x = 4·4
JL = 16
For this case we must find the value of the variable "p" of the following equation:
We apply distributive property on the left side of the equation taking into account that 
and 
:
We add similar terms:
We subtract 
from both sides of the equation:
We subtract 8 from both sides of the equation:
We divide by -6 on both sides of the equation:
